Though we cannot demonstrate this fact, yet there are many reasons to induce us to believe it: for the moon, though a secondary planet, is yet of considerable size;—and when viewed through a good telescope, its surface appears diversified, like that of the earth, with mountains and valleys. . . . Hence we are led to conclude that, like the earth, the moon also is inhabited.
